We have already spoken in such detail of tongue slips, and yet there are still several points to be added. Linked with tongue slips are smaller effective phenomena which are not entirely without interest. No one likes to make a slip of the tongue; often one fails to hear his own slip, though never that of another. Tongue slips are in a certain sense infectious; it is not at all easy to discuss tongue slips without falling into slips of the tongue oneself. The most trifling forms of tongue slips are just the ones which have no particular illumination to throw on the hidden psychic processes, but are nevertheless not difficult to penetrate in their motivation. If, for example, anyone p.r.o.nounces a long vowel as a short, in consequence of an interference no matter how motivated, he will for that reason soon after lengthen a short vowel and commit a new slip in compensation for the earlier one.

The same thing occurs when one has p.r.o.nounced a double vowel unclearly and hastily; for example, an "eu" or an "oi" as "ei." The speaker tries to correct it by changing a subsequent "ei" or "eu" to "oi." In this conduct the determining factor seems to be a certain consideration for the hearer, who is not to think that it is immaterial to the speaker how he treats his mother tongue. The second, compensating distortion actually has the purpose of making the hearer conscious of the first, and of a.s.suring him that it also did not escape the speaker. The most frequent and most trifling cases of slips consist in the contractions and foresoundings which show themselves in inconspicuous parts of speech. One's tongue slips in a longer speech to such an extent that the last word of the intended speech is said too soon. That gives the impression of a certain impatience to be finished with the sentence and gives proof in general of a certain resistance to communicating this sentence or speech as a whole. Thus we come to borderline cases in which the differences between the psychoa.n.a.lytic and the common physiological conception of tongue slips are blended. We a.s.sume that in these cases there is a tendency which interferes with the intention of the speech.

But it can only announce that it is present, and not what its own intention is. The interference which it occasions then follows some sound influences or a.s.sociative relationship, and may be considered as a distraction of attention from the intended speech. But neither this disturbance of attention nor the a.s.sociative tendency which has been activated, strikes the essence of the process. This hints, however, at the existence of an intention which interferes with the purposed speech, an intention whose nature cannot (as is possible in all the more p.r.o.nounced cases of tongue slips) this time be guessed from its effects.

Slips of the pen, to which I now turn, are in agreement with those of the tongue to the extent that we need expect to gain no new points of view from them. Perhaps we will be content with a small gleaning. Those very common little slips of the pen--contractions, antic.i.p.ations of later words, particularly of the last words--again point to a general distaste for writing, and to an impatience to be done; the p.r.o.nounced effects of pen slips permit the nature and purpose of the interfering tendency to be recognized. One knows in general that if one finds a slip of the pen in a letter everything was not as usual with the writer.

What was the matter one cannot always establish. The pen slip is frequently as little noticed by the person who makes it as the tongue slip. The following observation is striking: There are some persons who have the habit of always rereading a letter they have written before sending it. Others do not do so. But if the latter make an exception and reread the letter, they always have the opportunity of finding and correcting a conspicuous pen slip. How can that be explained? This looks as if these persons knew that they had made a slip of the pen while writing the letter. Shall we really believe that such is the case?

There is an interesting problem linked with the practical significance of the pen slip. You may recall the case of the murderer H., who made a practice of obtaining cultures of the most dangerous disease germs from scientific inst.i.tutions, by pretending to be a bacteriologist, and who used these cultures to get his close relatives out of the way in this most modern fashion. This man once complained to the authorities of such an inst.i.tution about the ineffectiveness of the culture which had been sent to him, but committed a pen slip and instead of the words, "in my attempts on mice and guinea pigs," was plainly written, "in my attempts on people."[20] This slip even attracted the attention of the doctors at the inst.i.tution, but so far as I know, they drew no conclusion from it.

Now what do you think? Might not the doctors better have accepted the slip as a confession and inst.i.tuted an investigation through which the murderer's handiwork would have been blocked in time? In this case was not ignorance of our conception of errors to blame for an omission of practical importance? Well, I am inclined to think that such a slip would surely seem very suspicious to me, but a fact of great importance stands in the way of its utilization as a confession. The thing is not so simple. The pen slip is surely an indication, but by itself it would not have been sufficient to instigate an investigation. That the man is preoccupied with the thought of infecting human beings, the slip certainly does betray, but it does not make it possible to decide whether this thought has the value of a clear plan of injury or merely of a phantasy having no practical consequence. It is even possible that the person who made such a slip will deny this phantasy with the best subjective justification and will reject it as something entirely alien to him. Later, when we give our attention to the difference between psychic and material reality, you will understand these possibilities even better. Yet this is again a case in which an error later attained unsuspected significance.

In misreading, we encounter a psychic situation which is clearly differentiated from that of the tongue slips or pen slips. The one of the two rival tendencies is here replaced by a sensory stimulus and perhaps for that reason is less resistant. What one is reading is not a production of one's own psychic activity, as is something which one intends to write. In a large majority of cases, therefore, the misreading consists in a complete subst.i.tution. One subst.i.tutes another word for the word to be read, and there need be no connection in meaning between the text and the product of the misreading. In general, the slip is based upon a word resemblance. Lichtenberg's example of reading "_Agamemnon_" for "_angenommen_"[21] is the best of this group. If one wishes to discover the interfering tendency which causes the misreading, one may completely ignore the misread text and can begin the a.n.a.lytic investigation with the two questions: What is the first idea that occurs in free a.s.sociation to the product of the misreading, and, in what situation did the misreading occur? Now and then a knowledge of the latter suffices by itself to explain the misreading. Take, for example, the individual who, distressed by certain needs, wanders about in a strange city and reads the word "_Closethaus_" on a large sign on the first floor of a house. He has just time to be surprised at the fact that the sign has been nailed so high up when he discovers that, accurately observed, the sign reads "_Corset-haus_." In other cases the misreadings which are independent of the text require a penetrating a.n.a.lysis which cannot be accomplished without practice and confidence in the psychoa.n.a.lytic technique. But generally it is not a matter of much difficulty to obtain the elucidation of a misreading. The subst.i.tuted word, as in the example, "_Agamemnon_," betrays without more ado the thought sequence from which the interference results. In war times, for instance, it is very common for one to read into everything which contains a similar word structure, the names of the cities, generals and military expressions which are constantly buzzing around us. In this way, whatever interests and preoccupies one puts itself in the place of that which is foreign or uninteresting. The after-effects of thoughts blur the new perceptions.

There are other types of misreadings, in which the text itself arouses the disturbing tendency, by means of which it is then most often changed into its opposite. One reads something which is undesired; a.n.a.lysis then convinces one that an intensive wish to reject what has been read should be made responsible for the alteration.

In the first mentioned and more frequent cases of misreading, two factors are neglected to which we gave an important role in the mechanism of errors: the conflict of two tendencies and the suppression of one which then indemnifies itself by producing the error. Not that anything like the opposite occurs in misreading, but the importunity of the idea content which leads to misreading is nevertheless much more conspicuous than the suppression to which the latter may previously have been subjected. Just these two factors are most tangibly apparent in the various situations of errors of forgetfulness.

Forgetting plans is actually uniform in meaning; its interpretation is, as we have heard, not denied even by the layman. The tendency interfering with the plan is always an ant.i.thetical intention, an unwillingness concerning which we need only discover why it does not come to expression in a different and less disguised manner. But the existence of this unwillingness is not to be doubted. Sometimes it is possible even to guess something of the motives which make it necessary for this unwillingness to disguise itself, and it always achieves its purpose by the error resulting from the concealment, while its rejection would be certain were it to present itself as open contradiction. If an important change in the psychic situation occurs between the formulation of the plan and its execution, in consequence of which the execution of the plan does not come into question, then the fact that the plan was forgotten is no longer in the cla.s.s of errors. One is no longer surprised at it, and one understands that it would have been superfluous to have remembered the plan; it was then permanently or temporarily effaced. Forgetting a plan can be called an error only when we have no reason to believe there was such an interruption.

The cases of forgetting plans are in general so uniform and transparent that they do not interest us in our investigation. There are two points, however, from which we can learn something new. We have said that forgetting, that is, the non-execution of a plan, points to an antipathy toward it. This certainly holds, but, according to the results of our investigations, the antipathy may be of two sorts, direct and indirect.

What is meant by the latter can best be explained by one or two examples. If a patron forgets to say a good word for his protege to a third person, it may be because the patron is not really very much interested in the protege, therefore, has no great inclination to commend him. It is, at any rate, in this sense that the protege will construe his patron's forgetfulness. But the matter may be more complicated. The patron's antipathy to the execution of the plan may originate in another quarter and fasten upon quite a different point. It need not have anything to do with the protege, but may be directed toward the third person to whom the good word was to have been said.

Thus, you see what doubts here confront the practical application of our interpretation. The protege, despite a correct interpretation of the forgetfulness, stands in danger of becoming too suspicious, and of doing his patron a grave injustice. Or, if an individual forgets a rendezvous which he has made, and which he had resolved to keep, the most frequent basis will certainly be the direct aversion to encountering this person.

But a.n.a.lysis might here supply the information that the interfering intention was not directed against that person, but against the place in which they were to have met, and which was avoided because of a painful memory a.s.sociated with it. Or, if one forgets to mail a letter, the counter-intention may be directed against the content of that letter, yet this does not in any way exclude the possibility that the letter is harmless in itself, and only subject to the counter-intention because something about it reminds the writer of another letter written previously, which, in fact, did afford a basis for the antipathy. One can say in such a case that the antipathy has here transferred itself from that former letter where it was justified to the present one in which it really has no meaning. Thus you see that one must always exercise restraint and caution in the application of interpretations, even though the interpretations are justified. That which is psychologically equivalent may nevertheless in practice be very ambiguous.

Phenomena such as these will seem very unusual to you. Perhaps you are inclined to a.s.sume that the "indirect" antipathy is enough to characterize the incident as pathological. Yet I can a.s.sure you that it also occurs in a normal and healthy setting. I am in no way willing to admit the unreliability of our a.n.a.lytic interpretation. After all, the above-discussed ambiguity of plan-forgetting exists only so long as we have not attempted an a.n.a.lysis of the case, and are interpreting it only on the basis of our general suppositions. When we a.n.a.lyze the person in question, we discover with sufficient certainty in each case whether or not it is a direct antipathy, or what its origin is otherwise.

A second point is the following: when we find in a large majority of cases that the forgetting of a plan goes back to an antipathy, we gain courage to extend this solution to another series of cases in which the a.n.a.lyzed person does not confirm, but denies, the antipathy which we inferred. Take as an example the exceedingly frequent incidents of forgetting to return books which one has borrowed, or forgetting to pay one's bills or debts. We will be so bold as to accuse the individual in question of intending to keep the books and not to pay the debts, while he will deny such an intention but will not be in a position to give us any other explanation of his conduct. Thereupon we insist that he has the intention, only he knows nothing about it; all we need for our inference is to have the intention betray itself through the effect of the forgetfulness. The subject may then repeat that he had merely forgotten it. You now recognize the situation as one in which we once before found ourselves. If we wish to be consistent in our interpretation, an interpretation which has been proved as manifold as it is justified, we will be unavoidably forced to the conclusion that there are tendencies in a human being which can become effective without his being conscious of them. By so doing, however, we place ourselves in opposition to all the views which prevail in daily life and in psychology.

Forgetting proper names and foreign names as well as foreign words can be traced in the same manner to a counter-intention which aims either directly or indirectly at the name in question. I have already given you an example of such direct antipathy. The indirect causation, however, is particularly frequent and generally necessitates careful a.n.a.lysis for its determination. Thus, for example, in war times which force us to sacrifice so many of our former inclinations, the ability to recall proper names also suffers severely in consequence of the most peculiar connections. A short time ago it happened that I could not reproduce the name of that harmless Moravian city of Bisenz, and a.n.a.lysis showed that no direct dislike was to blame, but rather the sound resemblance to the name of the Bisenzi palace in Orrieto, in which I used to wish I might live. As a motive for the antagonism to remembering the name, we here encounter for the first time a principle which will later disclose to us its whole tremendous significance in the causation of neurotic symptoms, viz., the aversion on the part of the memory to remembering anything which is connected with unpleasant experience and which would revive this unpleasantness by a reproduction. This intention of avoiding unpleasantness in recollections of other psychic acts, the psychic flight from unpleasantness, we may recognize as the ultimate effective motive not only for the forgetting of names, but also for many other errors, such as omissions of action, etc.

Forgetting names does, however, seem to be especially facilitated psycho-physiologically and therefore also occurs in cases in which the interference of an unpleasantness-motive cannot be established. If anyone once has a tendency to forget names, you can establish by a.n.a.lytical investigation that he not only loses names because he himself does not like them, or because they remind him of something he does not like, but also because the same name in his mind belongs to another chain of a.s.sociations, with which he has more intimate relations. The name is anch.o.r.ed there, as it were, and denied to the other a.s.sociations activated at the moment. If you will recall the tricks of mnemonic technique you will ascertain with some surprise that one forgets names in consequence of the same a.s.sociations which one otherwise purposely forms in order to save them from being forgotten. The most conspicuous example of this is afforded by proper names of persons, which conceivably enough must have very different psychic values for different people. For example, take a first name, such as Theodore. To one of you it will mean nothing special, to another it means the name of his father, brother, friend, or his own name. a.n.a.lytic experience will then show you that the first person is not in danger of forgetting that a certain stranger bears this name, while the latter will be constantly inclined to withhold from the stranger this name which seems reserved for intimate relationships. Let us now a.s.sume that this a.s.sociative inhibition can come into contact with the operation of the unpleasantness-principle, and in addition with an indirect mechanism, and you will be in a position to form a correct picture of the complexity of causation of this temporary name-forgetting. An adequate a.n.a.lysis that does justice to the facts, however, will completely disclose these complications.

Forgetting impressions and experiences shows the working of the tendency to keep unpleasantness from recollection much more clearly and conclusively than does the forgetting of names. It does not, of course, belong in its entirety to the category of errors, but only in so far as it seems to us conspicuous and unjustified, measured by the measuring stick of our accustomed conception--thus, for example, where the forgetfulness strikes fresh or important impressions or impressions whose loss tears a hole in the otherwise well-remembered sequence. Why and how it is in general that we forget, particularly why and how we forget experiences which have surely left the deepest impressions, such as the incidents of our first years of childhood, is quite a different problem, in which the defense against unpleasant a.s.sociations plays a certain role but is far from explaining everything. That unpleasant impressions are easily forgotten is an indubitable fact. Various psychologists have observed it, and the great Darwin was so struck by it that he made the "golden rule" for himself of writing down with particular care observations which seemed unfavorable to his theory, since he had convinced himself that they were just the ones which would not stick in his memory.

Those who hear for the first time of this principle of defense against unpleasant recollections by means of forgetting, seldom fail to raise the objection that they, on the contrary, have had the experience that just the painful is hard to forget, inasmuch as it always comes back to mind to torture the person against his will--as, for example, the recollection of an insult or humiliation. This fact is also correct, but the objection is not valid. It is important that one begin betimes to reckon with the fact that the psychic life is the arena of the struggles and exercises of antagonistic tendencies, or, to express it in non-dynamic terminology, that it consists of contradictions and paired antagonisms. Information concerning one specific tendency is of no avail for the exclusion of its opposite; there is room for both of them. It depends only on how the opposites react upon each other, what effects will proceed from the one and what from the other.

Losing and mislaying objects is of especial interest to us because of the ambiguity and the multiplicity of tendencies in whose services the errors may act. The common element in all cases is this, that one wished to lose something. The reasons and purposes thereof vary. One loses an object when it has become damaged, when one intends to replace it with a better one, when one has ceased to like it, when it came from a person whose relations to one have become strained, or when it was obtained under circ.u.mstances of which one no longer wishes to think. The same purpose may be served by letting the object fall, be damaged or broken.

In the life of society it is said to have been found that unwelcome and illegitimate children are much more often frail than those born in wedlock. To reach this result we do not need the coa.r.s.e technique of the so-called angel-maker. A certain remissness in the care of the child is said to suffice amply. In the preservation of objects, the case might easily be the same as with the children.

But things may be singled out for loss without their having forfeited any of their value, namely, when there exists the intention to sacrifice something to fate in order to ward off some other dreaded loss. Such exorcisings of fate are, according to the findings of a.n.a.lysis, still very frequent among us; therefore, the loss of things is often a voluntary sacrifice. In the same way losing may serve the purposes of obstinacy or self-punishment. In short, the more distant motivation of the tendency to get rid of a thing oneself by means of losing it is not overlooked.

Mistakes, like other errors, are often used to fulfill wishes which one ought to deny oneself. The purpose is thus masked as fortunate accident; for instance, one of our friends once took the train to make a call in the suburbs, despite the clearest antipathy to so doing, and then, in changing cars, made the mistake of getting into the train which took him back to the city. Or, if on a trip one absolutely wants to make a longer stay at a half-way station, one is apt to overlook or miss certain connections, so that he is forced to make the desired interruption to the trip. Or, as once happened to a patient of mine whom I had forbidden to call up his fiancee on the telephone, "by mistake"

and "absent-mindedly" he asked for a wrong number when he wanted to telephone to me, so that he was suddenly connected with the lady. A pretty example and one of practical significance in making a direct mistake is the observation of an engineer at a preliminary hearing in a damage suit:

"Some time ago I worked with several colleagues in the laboratory of a high school on a series of complicated elasticity experiments, a piece of work which we had undertaken voluntarily but which began to take more time than we had expected. One day as I went into the laboratory with my colleague F., the latter remarked how unpleasant it was to him to lose so much time that day, since he had so much to do at home. I could not help agreeing with him, and remarked half jokingly, alluding to an incident of the previous week: 'Let's hope that the machine gives out again so that we can stop work and go home early.'

"In the division of labor it happened that F. was given the regulation of the valve of the press, that is to say, he was, by means of a cautious opening of the valve, to let the liquid pressure from the acc.u.mulator flow slowly into the cylinder of the hydraulic press. The man who was directing the job stood by the manometer (pressure gauge) and when the right pressure had been reached called out in a loud voice: 'Stop.' At this command F. seized the valve and turned with all his might--to the left! (All valves, without exception, close to the right.) Thereby the whole pressure of the acc.u.mulator suddenly became effective in the press, a strain for which the connecting pipes are not designed, so that a connecting pipe immediately burst--quite a harmless defect, but one which nevertheless forced us to drop work for the day and go home.

"It is characteristic, by the way, that some time afterward when we were discussing this occurrence, my friend F. had no recollection whatever of my remark, which I could recall with certainty."

From this point you may reach the conjecture that it is not harmless accident which makes the hands of your domestics such dangerous enemies to your household property. But you can also raise the question whether it is always an accident when one damages himself and exposes his own person to danger. There are interests the value of which you will presently be able to test by means of the a.n.a.lysis of observations.

Ladies and gentlemen, this is far from being all that might be said about errors. There is indeed much left to investigate and to discuss.

But I am satisfied if, from our investigations to date, your previous views are somewhat shaken and if you have acquired a certain degree of liberality in the acceptance of new ones. For the rest, I must content myself with leaving you face to face with an unclear condition of affairs. We cannot prove all our axioms by the study of errors and, indeed, are by no means solely dependent on this material. The great value of errors for our purpose lies in the fact that they are very frequent phenomena that can easily be observed on oneself and the occurrence of which do not require a pathological condition. I should like to mention just one more of your unanswered questions before concluding: "If, as we have seen in many examples, people come so close to understanding errors and so often act as though they penetrated their meaning, how is it possible that they can so generally consider them accidental, senseless and meaningless, and can so energetically oppose their psychoa.n.a.lytic elucidation?"

You are right; that is conspicuous and demands an explanation. I shall not give this explanation to you, however, but shall guide you slowly to the connecting links from which the explanation will force itself upon you without any aid from me.

THE DREAM

FIFTH LECTURE

THE DREAM

_Difficulties and Preliminary Approach_

One day the discovery was made that the disease symptoms of certain nervous patients have a meaning.[22] Thereupon the psychoa.n.a.lytic method of therapy was founded. In this treatment it happened that the patients also presented dreams in place of their symptoms. Herewith originated the conjecture that these dreams also have a meaning.

We will not, however, pursue this historical path, but enter upon the opposite one. We wish to discover the meaning of dreams as preparation for the study of the neuroses. This inversion is justified, for the study of dreams is not only the best preparation for that of the neuroses, but the dream itself is also a neurotic symptom, and in fact one which possesses for us the incalculable advantage of occurring in all normals. Indeed, if all human beings were well and would dream, we could gain from their dreams almost all the insight to which the study of the neuroses has led.

Thus it is that the dream becomes the object of psychoa.n.a.lytic research--again an ordinary, little-considered phenomenon, apparently of no practical value, like the errors with which, indeed, it shares the character of occurring in normals. But otherwise the conditions are rather less favorable for our work. Errors had been neglected only by science, which had paid little attention to them; but at least it was no disgrace to occupy one's self with them. People said there are indeed more important things, but perhaps something may come of it.

Preoccupation with the dream, however, is not merely impractical and superfluous, but actually ignominious; it carries the odium of the unscientific, awakens the suspicion of a personal leaning towards mysticism. The idea of a physician busying himself with dreams when even in neuropathology and psychiatry there are matters so much more serious--tumors the size of apples which incapacitate the organ of the psyche, hemorrhages, and chronic inflammations in which one can demonstrate changes in the tissues under the microscope! No, the dream is much too trifling an object, and unworthy of Science.

And besides, it is a condition which in itself defies all the requirements of exact research--in dream investigation one is not even sure of one's object. A delusion, for example, presents itself in clear and definite outlines. "I am the Emperor of China," says the patient aloud. But the dream? It generally cannot be related at all. If anyone relates a dream, has he any guarantee that he has told it correctly, and not changed it during the telling, or invented an addition which was forced by the indefiniteness of his recollection? Most dreams cannot be remembered at all, are forgotten except for small fragments. And upon the interpretation of such material shall a scientific psychology or method of treatment for patients be based?

A certain excess in judgment may make us suspicious. The objections to the dream as an object of research obviously go too far. The question of insignificance we have already had to deal with in discussing errors. We said to ourselves that important matters may manifest themselves through small signs. As concerns the indefiniteness of the dream, it is after all a characteristic like any other. One cannot prescribe the characteristics of an object. Moreover, there are clear and definite dreams. And there are other objects of psychiatric research which suffer from the same trait of indefiniteness, e.g., many compulsion ideas, with which even respectable and esteemed psychiatrists have occupied themselves. I might recall the last case which occurred in my practice.

The patient introduced himself to me with the words, "I have a certain feeling as though I had harmed or had wished to harm some living thing--a child?--no, more probably a dog--perhaps pushed it off a bridge--or something else." We can overcome to some degree the difficulty of uncertain recollection in the dream if we determine that exactly what the dreamer tells us is to be taken as his dream, without regard to anything which he has forgotten or may have changed in recollection. And finally, one cannot make so general an a.s.sertion as that the dream is an unimportant thing. We know from our own experience that the mood in which one wakes up after a dream may continue throughout the whole day. Cases have been observed by physicians in which a psychosis begins with a dream and holds to a delusion which originated in it. It is related of historical personages that they drew their inspiration for important deeds from dreams. So we may ask whence comes the contempt of scientific circles for the dream?

I think it is the reaction to their over-estimation in former times.

Reconstruction of the past is notoriously difficult, but this much we may a.s.sume with certainty--if you will permit me the jest--that our ancestors of 3000 years ago and more, dreamed much in the way we do. As far as we know, all ancient peoples attached great importance to dreams and considered them of practical value. They drew omens for the future from dreams, sought premonitions in them. In those days, to the Greeks and all Orientals, a campaign without dream interpreters must have been as impossible as a campaign without an aviation scout to-day. When Alexander the Great undertook his campaign of conquests, the most famous dream interpreters were in attendance. The city of Tyrus, which was then still situated on an island, put up so fierce a resistance that Alexander considered the idea of raising the siege. Then he dreamed one night of a satyr dancing as if in triumph; and when he laid his dream before his interpreters he received the information that the victory over the city had been announced to him. He ordered the attack and took Tyrus. Among the Etruscans and the Romans other methods of discovering the future were in use, but the interpretation of dreams was practical and esteemed during the entire h.e.l.lenic-Roman period. Of the literature dealing with the topic at least the chief work has been preserved to us, namely, the book of Artemidoros of Daldis, who is supposed to have lived during the lifetime of the Emperor Hadrian. How it happened subsequently that the art of dream interpretation was lost and the dream fell into discredit, I cannot tell you. Enlightenment cannot have had much part in it, for the Dark Ages faithfully preserved things far more absurd than the ancient dream interpretation. The fact is, the interest in dreams gradually deteriorated into superst.i.tion, and could a.s.sert itself only among the ignorant. The latest misuse of dream interpretation in our day still tries to discover in dreams the numbers which are going to be drawn in the small lottery. On the other hand, the exact science of to-day has repeatedly dealt with dreams, but always only with the purpose of applying its physiological theories to the dream. By physicians, of course, the dream was considered as a non-psychic act, as the manifestation of somatic irritations in the psychic life. Binz (1876) p.r.o.nounced the dream "a bodily process, in all cases useless, in many actually pathological, above which the world-soul and immortality are raised as high as the blue ether over the weed-grown sands of the lowest plain." Maury compared it with the irregular twitchings of St.

Vitus' Dance in contrast to the co-ordinated movements of the normal person. An old comparison makes the content of the dream a.n.a.logous to the tones which the "ten fingers of a musically illiterate person would bring forth if they ran over the keys of the instrument."

Interpretation means finding a hidden meaning. There can be no question of interpretation in such an estimation of the dream process. Look up the description of the dream in Wundt, Jodl and other newer philosophers. You will find an enumeration of the deviations of dream life from waking thought, in a sense disparaging to the dream. The description points out the disintegration of a.s.sociation, the suspension of the critical faculty, the elimination of all knowledge, and other signs of diminished activity. The only valuable contribution to the knowledge of the dream which we owe to exact science pertains to the influence of bodily stimuli, operative during sleep, on the content of the dream. There are two thick volumes of experimental researches on dreams by the recently deceased Norwegian author, J. Mourly Vold, (translated into German in 1910 and 1912), which deal almost solely with the consequences of changes in the position of the limbs. They are recommended as the prototype of exact dream research. Now can you imagine what exact science would say if it discovered that we wish to attempt to find the meaning of dreams? It may be it has already said it, but we will not allow ourselves to be frightened off. If errors can have a meaning, the dream can, too, and errors in many cases have a meaning which has escaped exact science. Let us confess to sharing the prejudice of the ancients and the common people, and let us follow in the footsteps of the ancient dream interpreters.

First of all, we must orient ourselves in our task, and take a bird's eye view of our field. What is a dream? It is difficult to say in one sentence. But we do not want to attempt any definition where a reference to the material with which everyone is familiar suffices. Yet we ought to select the essential element of the dream. How can that be found?

There are such monstrous differences within the boundary which encloses our province, differences in every direction. The essential thing will very probably be that which we can show to be common to all dreams.

Well, the first thing which is common to all dreams is that we are asleep during their occurrence. The dream is apparently the psychic life during sleep, which has certain resemblances to that of the waking condition, and on the other hand is distinguished from it by important differences. That was noted even in Aristotle's definition. Perhaps there are other connections obtaining between the dream and sleep. One can be awakened by a dream, one frequently has a dream when he wakes spontaneously or is forcibly awakened from sleep. The dream then seems to be an intermediate condition between sleeping and waking. Thus we are referred to the problem of sleep. What, then, is sleep?

That is a physiological or biological problem concerning which there is still much controversy. We can form no decision on the point, but I think we may attempt a psychological characterization of sleep. Sleep is a condition in which I wish to have nothing to do with the external world, and have withdrawn my interest from it. I put myself to sleep by withdrawing myself from the external world and by holding off its stimuli. I also go to sleep when I am fatigued by the external world.

Thus, by going to sleep, I say to the external world, "Leave me in peace, for I wish to sleep." Conversely, the child says, "I won't go to bed yet, I am not tired, I want to have some more fun." The biological intention of sleep thus seems to be recuperation; its psychological character, the suspension of interest in the external world. Our relation to the world into which we came so unwillingly, seems to include the fact that we cannot endure it without interruption. For this reason we revert from time to time to the pre-natal existence, that is, to the intra-uterine existence. At least we create for ourselves conditions quite similar to those obtaining at that time--warmth, darkness and the absence of stimuli. Some of us even roll ourselves into tight packages and a.s.sume in sleep a posture very similar to the intra-uterine posture. It seems as if the world did not wholly possess us adults, it has only two-thirds of our life, we are still one-third unborn. Each awakening in the morning is then like a new birth. We also speak of the condition after sleep with the words, "I feel as though I had been born anew," by which we probably form a very erroneous idea of the general feeling of the newly born. It may be a.s.sumed that the latter, on the contrary, feel very uncomfortable. We also speak of birth as "seeing the light of day." If that be sleep, then the dream is not on its program at all, rather it seems an unwelcome addition. We think, too, that dreamless sleep is the best and only normal sleep. There should be no psychic activity in sleep; if the psyche stirs, then just to that extent have we failed to reduplicate the foetal condition; remainders of psychic activity could not be completely avoided. These remainders are the dream. Then it really does seem that the dream need have no meaning. It was different in the case of errors; they were activities of the waking state. But when I am asleep, have quite suspended psychic activity and have suppressed all but certain of its remainders, then it is by no means inevitable that these remainders have a meaning. In fact, I cannot make use of this meaning, in view of the fact that the rest of my psyche is asleep. This must, of course, be a question only of twitching, like spasmodic reactions, a question only of psychic phenomena such as follow directly upon somatic stimulation. The dream, therefore, appears to be the sleep-disturbing remnant of the psychic activity of waking life, and we may make the resolution promptly to abandon a theme which is so ill-adapted to psychoa.n.a.lysis.

However, even if the dream is superfluous, it exists nevertheless and we may try to give an account of its existence. Why does not the psyche go to sleep? Probably because there is something which gives it no rest.
